In such smallish areas, especially those with angled ceilings that are so closed in, the Audio Transducers hold a tremendous advantage over conventional speakers, both aurally and acoustically wise . In truth, I always enjoy cramming in a Theater in a small Bonus Room over a Garage. Great sound / Images in a room most would think wholly undesirable to consider for such use always seems to be greatly appreciated.

......and that my Fellow DIY HT Enthusiasts is what it is really all about.

It is. Anytime the ratio of Room volume to Transducer placement / quantity goes past a certain point, the effect becomes a immersive, virtual reality experience...with a totally seamless surround sound stage.
There's nothing like turning a Drywall wall into a screen AND a center channel in one fell swoop.

Now then....that's all I have to say about that. This is after all the DIY Screen Forum.
